Agricultural non-point source pollution surface runoff main water process monitoring device and method

Abstract

The invention provides an agricultural non-point source pollution surface runoff main water process monitoring device and method. The device includes first water quantity sensors which are arranged the outlets of runoff collecting tubes of surface runoff monitoring cells, and are used for obtaining surface runoff flow data and transmitting the surface runoff data to a wireless measurement and control module, second water quantity sensors which are arranged at outlets of irrigation water tubes at irrigation water openings of the surface runoff monitoring cells and are used for obtaining irrigation quantity data and transmitting the irrigation quantity data to the wireless measurement and control module, rainfall automatic monitors which are arranged at preset monitoring points and are used for obtaining rainfall data and transmitting the rainfall data to the wireless measurement and control module, the wireless measurement and control module which is used for receiving the surface runoff flow data, irrigation quantity data and rainfall data and transmitting the surface runoff flow data, irrigation quantity data and rainfall data to a remote receiving module, and the remote receiving module which is used for receiving the surface runoff flow data, irrigation quantity data and rainfall data transmitted by the wireless measurement and control module. With the agricultural non-point source pollution surface runoff main water process monitoring device adopted, real-time and automatic monitoring and remote transmission of monitoring data of an agricultural non-point source pollution surface runoff main water process can be realized, and monitoring results are more accurate.

Description

technical field [0001] The invention relates to the technical field of farmland non-point source pollution monitoring, in particular to a device and method for monitoring main water processes of farmland non-point source polluted surface runoff. Background technique [0002] At present, the loss of farmland nutrients into the environment has caused many problems such as eutrophication of surface water, excessive nitrate in groundwater, reduction of farmland production capacity, and decline of ecological environment quality. It is imperative to protect the water quality of water bodies and reduce the migration of farmland pollutants to water bodies. Only by monitoring farmland non-point source pollution and clarifying its occurrence process and development characteristics under different conditions can we formulate targeted non-point source pollution prevention and control strategies . At present, the devices and methods generally used for surface runoff monitoring of farmla...

AI Technical Summary

Problems solved by technology

[0004] In view of this, how to overcome the current problems such as the inability to monitor the main water processes of the surface runoff polluted by non-point sources in farmland in real time and the large error of monitoring results has become a technical problem that needs to be solved at present.
